SPRINKLER.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed January 10, 1914. Serial No. 811,499.

To all whom it may concern Be it known that we, GUADALUPE BUELNA and ALBERT BEVERLEY, citizens of the United States, residing at Santa Barbara, county of Santa Barbara, and State of California, have invented a certain new and useful Improvement in Sprinklers, of which the following is a specification.

Our invention relates to an irrigating de-v vice and has particular reference to a sprinkler of the revolving type for watering large areas.

Objects of this invention are to provide a sprinkling device in which the arms are actuated by positive means instead of by the reactive force of the water and in which the water may be regulated to govern the actual ing mechanism, whereby the quantity of water thrown by the sprinkling arms may be increased in inverse proportion to the amount used or required for controlling the actuating mechanism.

With these and other objects in view this invention consists of the features, details of construction and combination of parts de scribed in connection with the accompanying drawing and then more particularly pointed out in the claims.

In the drawing, Figure 1, is a vertical sectional elevation showing our invention. Fig. 2, is a plan view, showing the lower section of the casing, the inlet through the partition, and the vertical wall rising from said partition, and Fig. 3, is a perspective view of the disk piston for imparting revoluble motion to the sprinkler.

Referring to the drawing, the casing comprises two flanged sections 1 and 2, secured together by screws 3, the lower section 2, being provided with an internally threaded extension 1, for connection with a service water pipe 5. Integral with the interior of said lower section 2, is a partition 6, whichinclines downwardly from the center, and is provided centrally thereof with a concavity 7, and at one edge of its circumference with a water inlet port 8, and a vertically rising wall 9, disposed immediately adjacent one side of said port 8. The upper edge of said lower section 2, of said casing, is rabbeted as at 10, and forms a seat for the correspondingly rabbeted edge of an annular partition 11, whose plane inclines upwardly from the center, the center of which partition is provided with an orifice 12, whose l walls 13, are curved to conform to the cur vature of and form a snug seat and bearing for the upper part of a i. all 1 1, constituting the central axis of a disk piston 16, while the lower part of said ball 14., is seated in said concavity '1', in the partition 6. The partition 11, forms with said partition 6, an annular disk-chamber 17, in which the nutations of the disk piston under the impulse of the flowing water, occur. The piston 16, is slotted at 18, to straddle the wall 9 and thereby prevent axial revolution of said disk yet leave it free to operate under the pressure of the water, the wall being provided to divide the chamber 17 to cause a constant flow of water in one direction. The disk 16, on each side of said slot 18, is provided with peripheral notches l9 and 20, forming passageways for the water, these passageways being normally in register with the port 8, in the partition 6, and with the port 21, in the partition 11, respectively, thelatter port 21, lying normally immediately adjacent said wall 9. The partition 11, normally rests loosely on the rabbeted edge 10, of the lower section 2, of the casing, being held in position when the parts are assembled, by the upper section 1. This provision is made for the purpose of enabling the said partition 11, to be moved, so that its port 21 is carried over the wall 9 and a portion thereof is made to lie directly above the port 8, in the partition 6. In this manner, a greater quantity of water may pass directly through the ports 8 and 21, with practically the same initial force and velocity with which it enters the chamber 17, while but a small quantity of water is diverted for the operation of the disk piston 16. It is obvious that where the quantity of water used for operating the disk piston is reduced, the speed of the disk piston will also be reduced proportionably.

On the aforementioned ball 14, of the disk piston 16, is a spindle 22, which ex-- tends through the orifice 12, in said partition 11, and in operative relation to a horizontal bar 23, fixed on the end of a vertical arbor 24, suitably supported in a cage 25, which is internally threaded and arranged to be screwed on a threaded extension 26, on said partition 11. On said arbor 24;, is a pinion 27, for transmitting movement, through a train of gears 28, on the top of said cage 25, to a pinion 29, in mesh with an annular geared disk 30, supported within said casing by a shoulder 31, on the end of a pipe 32 which extends through and beyond a hollow extension 33, integral with said casin section 1. That portion of the pipe 32, which extends beyond the extension of the casing, is threaded as at 34, toreceive a head carrying nozzles or water conducting arms 36. Said geared disk 30, is frictionally connected with the pipe 32, for the purpose of permitting movement of the pipe independently on the said geared disk, and thus preventing injury to the gears. Normally the head 35, rests on the end of the extension 33, but during the passage of water through the sprinkling arms 36, the shoulder 31, on the pipe 32, is held by the water pressure in engagementwith the geared disk 30, which, actuated by the pin ion 29, causes a revolution of said pipe and its head 35.

hat we claim, is

1. In a sprinkler, the combination with a sectional casing, the lower section of which is provided with a fixed partition having a wall rising "ertically therefrom and a port adjacent said wall, of a ported partition within said casing and movable with re' spect to said fixed partition and forming therewith an annular chamber, a disk piston within said chamber having a spindle, a pipe in and projecting beyond the upper end of said upper section and provided with a head, a gear disk frictionally connected with said pipe, a pinion in mesh with said gear disk, and means controllable by said spindle to actuate said pinion and transmit revoluble motion to said gear disk and pipe.

2. In a sprinkler, the combination with a casing, arranged for attachment to a water service pipe, a pipe extending through said casing and provided with a head, a gear frictionally mounted on said pipe, means to revolve said gear, a disk piston controllable by water pressure to operate said revolving means, and means to regulate the quantity of water utilized to actuate the disk piston in proportion to the entire quantity of water passing through the device.

3. In a sprinkler, the combination with a sectional casing arranged for attachment to a service water pipe, the lower section of said casing having a fixed partition and a vertically rising wall and provided with a port adjacent said wall, an axially movable ported partition resting on said lower section and held in position by said upper section, said movable partition forming with said fixed partition a chamber, a disk piston in said chamber having a slot straddling said wall to prevent axial rotation thereof, said disk piston being provided on each side of said wall with anotch normally in register with the ports in said fixed and movable partitions, a pipe extending through the upper section of said casing, a head on said pipe provided with water conducting arms, a gear within the upper section of said casing frictionally attached to said pipe, means to actuate said gear and pipe, and means controllable by said disk piston to operate said gear and pipe actuating means.

4. In a sprinkler, the combination with a casing arranged for attachment to a service pipe, of a pipe within and extending from said casing, a head on said pipe provided with water conducting arms, a gear within said casing and frictionally attached to said pipe, water controlled means to revolve said gear and pipe, and means to regulate the flow of water through the device whereby the rate of discharge is varied inversely as the speed of rotation.

In testimony whereof we afiix our signatures in the presence of two witnesses.
